Abstract: A regulating unit senses the pressures in two zones of a recirculation passage to create a control pressure, and a transducer regulates an operating pressure which positions a control valve to provide exhaust gas recirculation at rates which establish the pressures in the zones necessary to maintain the control pressure equal to a reference pressure. Exhaust gas recirculation thus varies with engine exhaust backpressure and accordingly is a proportion of induction air flow with the proportion being ruled by the regulating unit.

Abstract: A pressure regulating valve assembly includes a valve body mounting an electric solenoid assembly. The solenoid assembly controls the fluid pressure in a chamber defined in the valve body. Fluid in the chamber is biased against a deflectable disc which controls fluid flow through the valve assembly. Control of electric current to the solenoid assembly controls fluid pressure in the chamber and, thus, fluid flow through the valve assembly. When utilized with a damper and a controller, the present valve assembly provides continuously variable damping in real time.

Abstract: An electro-hydraulic pressure regulating valve including a tubular valve body, a partition in the valve body dividing the latter into a valve chamber and a solenoid chamber, a valve sleeve in the valve chamber with a piston slidable in the sleeve and defining a bias pressure chamber between the piston and the partition and a control pressure chamber on the opposite side of the piston, closed center regulating ports on the piston and the valve sleeve for regulating a supply pressure to a control pressure in the control pressure chamber, a bias pressure orifice between a supply pressure port and the bias pressure chamber, a fluid strainer between the supply pressure port and the bias pressure orifice, a relief orifice in the partition between the bias pressure chamber and a fluid sump, and a solenoid operated valve normally closing the relief orifice and operative when energized to open the relief orifice. The valve is suited for miniaturization and regulates control pressure as a function of bias pressure without exhausting significant quantities of supply pressure directly to the sump.

Abstract: An electromagnetic fuel injector has a thin orifice director plate, mounted downstream of the orifice passage defined when the solenoid actuated valve of the injector is in the open position relative to its associated valve seat, for controlling static flow from the injector. The thin orifice director plate is provided with upset angled portions having the flow orifice formed at right angles therethrough to direct the jets of fuel flow, as desired, relative to the axis of the spray tip discharge passage of the injector. Preferably, the length (L) to diameter (D) ratio of each flow orifice is 0.5 or less.

Abstract: To measure the mass air flow in the induction passage of an engine, a small venturi located centrally in the passage serves as an air sampling tube. A slotted aperture in the wall of the tube at the venturi throat allows a hot film sensor to extend into the venturi throat from a support such as a printed circuit board mounted outside the venturi. The film sensor is in the form of a loop supported only at its ends on the support. The loop comprises a substrate of flexible insulating film material coated with an electrical resistance layer forming the active element of the sensor. The loop has a major dimension extending arcuately and transversely of the air flow through the venturi and a minor dimension extending parallel to the air flow.

Abstract: A valve controlling the rate of air flow from a supply pump to an engine exhaust system directs the air flow to the exhaust system through an orifice in a diaphragm valve which is associated with a valve seat separating the air supply from an excess air discharge port. The pressures acting on the diaphragm displace the diaphragm from the valve seat the amount necessary for the rate of air flow through the orifice to the exhaust system to be proportional to the rate of exhaust flow through the exhaust system and for the excess air flow supplied by the pump to be discharged through the excess air port.

Abstract: During operation of an internal combustion engine at low temperatures, the carburetor choke is closed to the extent necessary to provide the fuel which will maintain the mean effective pressure of combustion equal to the mean effective pressure occurring during operation at normal temperatures. The torque produced during low temperature engine operation is thus maintained equal to the torque produced during operation at normal temperatures.

Abstract: An electronic throttle body fuel injection system in which a fuel pump delivers fuel at constant flow and pressure to a jet in a pressure controlled chamber which is continuously ported upstream of the jet discharge to a fuel nozzle in a throttle bore and is periodically ported to bypass back to the pump fuel supply by an electrically operated on-off valve. The valve has an atmospheric reference pressure bias and is operable with a fuel demand signal from a conventional electronic fuel injection control system to open and close for time periods which vary with the fuel signal to vary the pressure in the controlled chamber between a value which induces fuel flow through the fuel nozzle for such time periods and a value which does not to thereby effect a metered flow to the fuel nozzle according to the fuel demand signal to provide the desired air/fuel ratio for optimum engine running conditions.

Abstract: A switching member simultaneously establishes a reference pressure and selects the pressure in one of two zones of a recirculation passage to create a control pressure, and a transducer regulates an operating pressure which positions a control valve to provide exhaust gas recirculation at rates which establish the pressures in the zones necessary to maintain the control pressure equal to the reference pressure. Exhaust gas recirculation thus varies with engine exhaust backpressure and accordingly is a proportion of induction air flow with the proportion being ruled by the switching member.
